These 1.5V rechargeable lithium AA batteries are best for devices that want alkaline-like voltage, especially Xbox controllers, Blink cameras, smart locks, and other higher-draw gear. The built-in holder doubles as the charger, which makes the set convenient, and several reports say runtime is strong, with some devices lasting weeks or months and holding 1.5V better than NiMH cells. The main cautions are the sudden drop-off at end of charge, limited warning before shutdown, and the need for the right lithium-compatible charger and charging habits. A few packs also arrived dead or failed after a short time.
Common Questions (5)
They can last much longer than NiMH cells in higher-voltage devices, with reports of weeks to months of use in Xbox controllers and smart locks, and several months in a Flume leak detector. In Blink cameras, they work well for some setups but may still last less than disposable Energizers in harder-to-reach cameras.
Yes, the case is meant to be powered by USB-C and the listing calls for a 5V/3A supply. A lower-amp charger will still work but can take all day, while a charger above 3A is generally fine because the device only draws what it needs.
Yes. They hold a steady 1.5V until the internal cell is depleted, then can shut off abruptly, so devices may give little or no low-battery warning. That makes them great for devices that want full voltage, but less predictable for gear that depends on gradual voltage decline.
No. They need a charger designed for 1.5V lithium cells, and using a NiMH charger can overcharge the wrong chemistry and create a fire risk. A proper smart charger or the included charging case is the safe option.
A test with an XTAR VX2 Pro measured about 2000-2100 mAh, or roughly 2800-2900 mWh, at a 300mA discharge rate. That is below the headline 3000mWh claim, but still enough to outperform many NiMH AAs in devices that need a full 1.5V output.

I use similar (1.5V Lithium) batteries in my Quest controllers. When I get a low-battery warning for my controller, I have about 10 minutes left due to their steep voltage drop-off.
Not trying to train my family that they have to only use specific batteries in a specific charging case with a specific usb-c psu, or else risk a lithium fire. Hard pass.

WH is it an actual unit of power.
